Title: Method and device for polishing wafer
Inventor: KITSUTA SATORU
IPC: B24B37/07
Filed: 1987-10-28
Abstract: PURPOSE:To enable a wafer to be high accurately polished by gluing the wafer to the bottom surface of a rotatable plate and applying the predetermined pressure of fluid uniformly acting on the upper surface of the plate so that the plate substantially eliminates its flexing deformation holding flatness to a high degree. CONSTITUTION:A polishing device, gluing a wafer W to the bottom surface of a plate 1, placing it on a turn table 3 with this wafer glued surface in the bottom and pressing the plate 1 by a top ring 8 forming its bottom part into a reversed dish shape, performs mirror polishing of the wafer W by relatively slipping the wafer W with the turn table 3. The device, which provides a flexible thin film (pressing plate) 11 extending in the bottom surface or the top ring 8 to form enclosed space 12, presses the plate 1 by supplying pressure fluid to the enclosed space 12 from a fluid supply source. The pressure of this pressure fluid is adjusted by a pressure adjusting mechanism 13, and the device, applying a uniform pressure acting on the upper surface of the plate 1 and placing it in a condition generating no flexing deformation, polishes the wafer with high accuracy.

Title: Surface treatment for terminal of component to be mounted on printed board
Inventor: FURUKAWA TERUMI
IPC: C25D7/00
Filed: 1995-10-23
Abstract: PROBLEM TO BE SOLVED: To prevent solder from adhering to the leading edge of a terminal by performing surface treatment on the leading edge of the terminal for suppressing solder adhesion. SOLUTION: When a main body 2, which has a terminal 8 to be surface- treated, is to be mounted on a printed board 4 and fixed by soldering, the L-shaped terminal 8 is inserted into the through hole 5 of the printed board 4. Then, a part close to the leading edge part 8b of the terminal is bent inside or outside so as to prevent the generation of float of the main body 2 when the main body 2 is soldered, and soldering is performed. At that time, since the base part 8a of the terminal is plated with solder, tin, gold, silver, etc., that have high solderability, the base part 8a can be easily soldered at the part of the through hole 5 of the printed board. Since the leading edge part 8b of the terminal is plated with nickel, to which solder does not easily adhere, the base part 8a repels solder, and even when a via hole 6 is present close to the leading edge part 8b of the terminal, the leading edge part 8b of the terminal and the via hole 6 are not bridged by solder. Thus, modification is not necessitated in the assembly process.

Title: Detecting device for change in condition in room
Inventor: TAKAHASHI YUTAKA
IPC: G08B13/16
Filed: 1994-11-10
Abstract: PURPOSE: To surely detect the abnormal state of an object to be detected by comparing a standard wave time series signal stored in advance and a reflection wave time series signal to judge the abnormal state and outputting an alarming signal. CONSTITUTION: Ultrasonic wave transmitted from a transmitter 11 is multiply reflected at every place in a room 1 and received by a receiver 12. At this time, when nothing is changed in the room 1, the reflected wave to be received by the receiver 12 is repeatedly received in a fixed waveform. But when a window glass 2 is broken or a door 3 is opened, since the route of the reflected ultrasonic wave is changed, the reflected wave time series signal received by the receiver 12 largely changes. Consequently, when this changed reflected wave time series signal is inputted to a controller, the signal is compared with the standard wave time series signal without abnormality there. But significant difference is generated between both signals as a matter of cource so that the alarm signal is outputted by an alarm device.  Thereby, the opening state of the window glass 2 and the door 3 can be known.
